It's an extremely mild abrasive in this form (of vinegar, yep) - some folks dilute baking soda in vinegar, I feel that's too coarse myself. One of the mildest silver polishes I know about and use, Blitz (not Flitz) is still grittier than ketchup in your fingers. I only use organic, free range grass fed no corn syrup ketchup, my metal is pampered. /s ;) (you just use your fingers or qtips for the crevices, then wash in warm soapy water, dry well then plop into a sealed glass jar of acetone for a few days)
